"I do not need to defend myself for having written this book. If its doctrines are biblical, public rejection will not concern me. However, if they are not biblical, then no defense could ever justify them! I have wanted to declare the teachings of the gospel not only in theoretical form, but in practical form and to demonstrate their value for the Christian experience. I am completely persuaded that the truths of sovereign grace, far from making believers negligent, are for the comfort and holiness of sinful but forgiven men. If I were not persuaded of that, I would never again speak or write these truths" Abraham Booth
The author expounds on the theme of grace, to apply it to every area of our salvation in Christ. Thus, he touches on the topics of election, calling, forgiveness, justification, adoption, sanctification, assurance, and the glorification of the believer, all related to God's grace.
